Removed the starter motor with difficulty. Having a look in the workshop to see if anything wrong. Connected to battery and works fine.... so I wonder what is preventing working in the boat. Seems to be a Kubota 1kw. 

Next job to check the wiring. Seems to be a wiring fault, because it all works on the bench and now back in the boat. Went for a trial run and starting no problem.

Time to take off on my own for a trip upstream. A bit nervous about handling the ropes through the locks but there was no need!

No parking for the car at Bossoms so a bit of a delay until 12.15. Spotted Tarsus (my father’s old boat) on the other side of Godstow lock. Police divers at Godstow bridge - thought it might be a body but lock-keeper informed me that they were simply cleaning up the river. Diver swam to the bank and allowed me to pass under the bridge.

Encountered rather rude (later apologised) narrow boat. They only left one half of the lock gates open and I had to tie up and open up the other half. One gate is not enough for Aviva. Whilst fiddling about in the lock (keeper was at lunch), Environment Agency boat turned up. Pleasant chat with the skipper.

I took a photo of the Albin Marin plate on Aviva. Number 1163. A previous owner has documented the year as 1973 but I cannot confirm this.
This etched brass plate has really nice typography, with the main text set out in (what appears to be) the Optima typeface; like this:
